Laptop M.2 NGFF SSD Compatibility List

The M.2 port is originally called NGFF port. It is a new-generation port standard which is specially designed for the laptop to supersede the mSATA port. The M.2 port is much better than mSATA with either regard to its smaller size or higher transferring performance.

M.2, as a new port standard that Intel has launched to replace mSATA, is also called NGFF – Next Generation Form Factor that we always mentioned in the past. As a matter of fact, for desktop users, the SATA port can meet most of their demands. But considering to satisfying Ultrabook user’s requirement on storage, Intel desperately has released this new port standard. Although we see this new M.2 port on the new 9 series motherboards launched by Asus, Gigabyte and MSI, this new port means little to the desktop computer. M.2 port’s real meaning can only be reflected on Ultrabook that Intel mainly intends to launch.

Compared with mSATA SSD, M.2 SSD has the speed advantages. The M.2 port has two types: Socket 2 and Socket 3. The Socket 2 supports SATA and PCI-E x 2 port standard, But if adopting PCI-E x 2 port standard, its read speed can reach up to 700MB/s while its write speed can reach 550MB/s. Socket 3 can support PCI-E x 4 port, and its theoretical bandwidth can reach 4GB/s.

M.2 SSD has three different types of “keys”, they are respectively is B, M and B&M.
